This is a (compiled) backup of the Totse.com BBS/textfiles website as it is provided in the (now dead) torrent for it. Archive is in RAR format, the exact method of downloading the backup is unclear.
According to the readme contained in the archive, "The forum archives came from numerous sources and is not complete. They are more difficult to navigate because they were not all ripped properly. There are over thousands of working threads in the community folder but not every link works."
